Research Background

Advantage of stereolithography
Fabrication of 3D models whose size are 100 nm to 100 cm is available using photopolymer.
  1. Realization of both high speed and high spatial resolution is difficult
    Limitation of linewidth due to the diffraction limit of light, Limitation of scanning speed attributable to sensitivity of photopolymer
  2. Surface roughness is limited due to accumulation of multiple layers
  3. Available materials are limited


  • Tunable linewidth depending on model shape and scale
  • Reduction of fabrication time
  • Realization of omnidirectional 3D fabrication for making smooth surface
  • Creation of functional devices using ceramics
  • Development of artificial organs using hydrogel materials
